“Question: If someone who has just been acquitted of murder is called murderer — is it slander?”
It’s an astonishing assertion to make publically. You’re correct, a jury found him not guilty. I’d say this is just a minor ethical transgression compared with the others. I’m guessing she’s in line for censure. Possibly, disbarment. She appears to be trying to justify her actions. At this point, she should remain silent and possibly get her own lawyer.
That should get her a gig as a 'legal analyst' for one of the networks.
